iOS 常用宏定义汇总 【持续更新】

获取屏幕 宽度、高度

#define Screen_Width ([UIScreen mainScreen].bounds.size.width)

#define Screen_Height ([UIScreen mainScreen].bounds.size.height)

RGB颜色

#define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]

debug输出

#ifdef DEBUG

#   define NSLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);

#else

#   define NSLog(...)

#endif

判断系统版本

#define IOSVersion [[[UIDevice currentDevice] systemVersion]  floatValue]

#define CurrentSystemVersion [[UIDevice currentDevice] systemVersion]

#define IsIOS7_0Later !(IOSVersion < 7.0 )

#define IsIOS8_0Later !(IOSVersion < 8.0 )

获取应用当前版本

#define VERSION [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey]

判断设备

// 是否iPad

#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

// 是否iPad

#define someThing (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)? ipad: iphone

//获取设备当前语言

#define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])

//判断是否 Retina屏

#define isRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) : NO)

定义UIImage对象 

//建议使用前两种宏定义,性能高于后者

#define LOADIMAGE(file,ext) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:file ofType:ext]]

#define IMAGE(A) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:A ofType:nil]]

#define ImageNamed(_pointer) [UIImage imageNamed:[UIUtil imageName:_pointer]]

 

由角度获取弧度 有弧度获取角度

#define degreesToRadian(x) (M_PI * (x) / 180.0)

#define radianToDegrees(radian) (radian*180.0)/(M_PI)
